TAB Services Company

What TAB Services Company does

TAB Services Company, founded in 1981 and headquartered in Denver, Colorado, is a privately held mechanical services firm specializing in HVAC testing, adjusting, and balancing (TAB) for commercial and institutional facilities. The company independently verifies that critical mechanical systems perform as designed across five interconnected service lines: HVAC TAB (air and hydronic balancing, duct leakage testing, sound and vibration analysis, control system verification) as the foundational offering; critical area pressure testing for healthcare facilities; biological safety cabinet and fume hood testing to NSF/ANSI 49 and ASHRAE 110; fire and life safety inspections against NFPA and Joint Commission standards; and specialized consulting covering design review, equipment sourcing, and HVAC commissioning. Service delivery relies on specialized air and hydronic flow measuring equipment that is annually calibrated by independent third parties, deployed by technicians holding NEBB, ICB/TABB, and OSHA credentials.

The firm serves healthcare, government, aviation, defense, telecommunications, pharmaceutical, education, hospitality, and commercial office clients across a six-state Rocky Mountain footprint (Colorado, Wyoming, Utah, New Mexico, Kansas, Nebraska). Disclosed project work spans institutions such as the Rocky Mountain Regional VA Medical Center ($1.7M+), Denver Health Hospital ($1M+, 15+ year ongoing relationship), Denver International Airport ($1M+ combined), Lumen Technologies ($2.5M+ combined), Lockheed Martin, Amgen Pharmaceuticals, Denver Public Schools, and the Arraj U.S. Courthouse. Customer acquisition is relationship-driven, with direct engagement of facility managers, building engineers, government contractors, and general contractors, supplemented by a website quote request system and dedicated inbound channels.

Revenue is generated through project-based professional services engagements priced by scope, ranging from one-day reports to multi-year complex-facility projects, with multi-year contracts common for institutional clients. The company self-describes as the largest TAB firm in the Rocky Mountain region, having completed over 7,000 projects since founding and fielding a team with 200+ combined years of technical balancing experience. Leadership comprises President Chris Lau (CPA, 12 years of business management experience) and Vice President Josh Uncapher (apprentice since 1999, now leading operations and quality control). TAB Services is management-owned, holds no patents, has no external funding, and operates without a parent entity.
